When I used to work for a well known transport company I had what we called "P60 Holiday & Sick Pay".
Basically, if your basic pay was say £18k a year and you worked overtime and your P60 came in at a higher rate like £26k - Your holiday pay instead of being £69.23 a day was £100.
(Un)fortunately, this applied to sick pay also. The amount of people who took 26 weeks off every other year on the 'sick' was unbelievable. It amazed me how people exploited this, it was dirty beyond belief.
The companys' solution to this was to make those on the 'better' contract working conditions intolerable. It worked on me very well...
muon - You'd be surprised at how far companies are willing to go to screw you over.
They basically cut our department to shreds, stopped over-time and then 'disciplined' people for not getting their job done, even if everyone from the bottom to middle management told them it wouldn't work without extra staff or overtime. We got a set of new 'blue chip' contracts - a department of 3 people when we were already struggling with what we had.
I ended up doing 70+ hour weeks, sometimes with only 8 hours between Week 1 & Week 2. Now they have 10 people in this department doing the same thing we were doing with 3 and they STILL are failing. The main office in England found out I left (the then manager didn't even tell customers I wasn't the contract contact anymore and the complaint escalated) and launched an investigation and 8 people got sacked over the head of it.
ANYWAY - It is a really nice reward for putting effort into the job, it just gets ruined by those taking the mick out of it.
Sorry for the wall of text, but I loved that job and haven't really spoken about what went on then - Got annoyed
