Sorry, you're mistaken.
Let me clarify and be more accurate since you provided no specifics but generalities.
- loss of wages for 5 1/2 weeks based on $40,000 per year is $4,231
- it's 6% over 3 years, not just in the first year as you state, therefore increase is $2,400
- strike pay is $1,100
Therefore, loss is $4,231 -$2,400 - $1,100 = $731
Protecting sick days is not a gain, but status quo. Also pension is based on the best 5 consecutive years salary, not including overtime, strike pay, etc.. The key word is consecutive so this year will be a low one so they will have to start all over again and in five more years it will become financial beneficial for them. That's assuming the pension stays the same which can easily change due to the economy and will probably be on the agenda for change on the next round of negotiations in 3 years.
So, you're comment about the union won by a mile is slightly embellished, lol.
