im after some advice on my situation
I started a new job with my current employer back in October last year, everything is ok although im not as keen as I was with this new job as I feel more of a glorified warehouse op than what the title suggests.
I left my old company because I couldn't see any progression there with the current situation of the people above me having served 15+ years and not likely to leave within the next 15 to 20 years and I was only a warehouse op and other team leader jobs in the manufacturing department were taken with no one really looking to leave and me not having any experience in those sectors.
Now comes my dilemma, my old boss has contacted me and has offered me the chance to return to my former company but this time as a manufacturing team leader for the Injection Moulding section after they had a surprise resignation, I met with my former boss and he outlined everything that I can do which would save them around 6-9 months worth of training and offered to send me on courses and training to learn the moulding machines if I accept.
This was also on top of a big increase of salary which will be an extra 33% on top of what I currently earn and will mean within 6 months my salary jumping a whopping 40% on what I used to earn 4/5 months ago.
Although I am keen to learn and take this opportunity with a company I like and know,
I don't want to make my new place of work and bosses feel like I have wasted their time and wondering if I should take the job opportunity.
Any advice out there for me? Thanks
