I was let go from my previous place of employment around two months ago. It was a pretty quick process- I was called in to the managing directors office in the afternoon, informed I was being let go, and then back to my desk to get my things and leave.
There was no disciplinary procedure involved, I was not given any specifics as to why I was being let go. I did ask if they had been unhappy with my performance or whether they just no longer wanted to pay the development costs for the back-office system for which I was the sole developer (I suspect they felt it would be cheaper to buy in separate modules that did everything the current system did, rather than pay my salary to continue developing it). The answer I received was a rather vague "A bit of both", in that whether or not my performance was an issue (and I should mention that up until that point, it had never been brought into question) they weren't getting the turnaround speed on features that they had hoped for.
I was disappointed but chalked it up to a lesson in managing expectations and moved on. As I had not been working there for 2 years I was not eligible for redundancy pay (I'm not even sure it was a redundancy, the word was never used). I was told they would pay my notice period but that I did not have to come into the office, and that I was on gardening leave. I spent the time to search for a new job, they were happy to provide a good reference- and I thought that was that- however when the final pay transfer went into my bank account it was far lower than I had been expecting.
I e-mailed their finance department and asked for copies of my pay slips (they used an electronic system, and as I had left the office quite quickly ne'er to return , I hadn't thought to print off hard copies). I was e-mailed my final 3 pay slips, the last one detailed 2 units (weeks) of pro-rata work before I was let go, 4 units of notice period paid at less than half the normal rate, and the days holiday I was owed in lieu. All told I appear to be missing over £1200 from the half pay notice period. At no point in the (short) meeting was it mentioned that it would be half pay, and I would not have agreed if it was. Nothing in my contract suggests they can pay half rate. It does mention they can dismiss a employee immediately (or put them on gardening leave) by paying the sum of their notice period.
I e-mailed their finance department about the discrepancy but have yet to receive a response and I'm curious as to my next move. My instinct is to contact the Citizens Advice Bureau, but I am wondering if there are other steps or precautions I should be taking beforehand.
