This question already has an answer here:
I work in 3rd line technical support for a large multi national (non IT) company in the UK.
I am one of four engineers/developers with a varying mix of knowledge, expertise and experience. I am the youngest with only 10 years work experience as technical support, but 6 in this current employer. Whilst the other three have more experience than me (20-30 years+)
All four of us currently have had an unspoken arrangement whereby we have all been 'on call' for the last 6 years and not getting paid any extra, we have all just seen this as part of the job as there is no real alternative as other members of the IT team in the company do not have the detailed knowledge or access to the systems that we posses.
Management now want a proper process in place for us four engineers/developers to be on call out of hours sharing the responsibility 25% each. The company have other employees in other parts of the business in similar situations and management have told us that they are paid rather handsomely on top of their annual salary if they are called or not. They are proposing a similar situation with us four.
The companies definition of on call is just to be available within 15 minutes of accepting the initial call. We must accept the call within a reasonable time. IE it is acceptable to miss a call at 3am but to phone back within a reasonable amount of time after being woken up. We are not expected to stay awake when on call.
I have no reference point when it comes to being on call. I feel I could charge whatever I wish and the company will accept any amount I request as they have done so in the past when negotiating salaries. They do not have any other option as far as we see. But yet I do not want to seem to be greedy or over the top. I was thinking an additional 10% - 20% of my annual salary.
What is a typical on-call rate for this type of scenario?
UPDATE - June 2019:
I am now receiving 25% of my annual salary for being on call 50% of the year, but in reality I rarely get called out so seems reasonable and fair for my circumstances.
