Who paid into the GMB war chest in the first place? Let's illustrate how ignorant this is with some very basic maths:And then paid overtime to clear the backlog. Out of pocket? No. Quids in? Yes.
1) Paid £100 a week for a year and 12 weeks: 64 x £100 = £6400
2) a) Paid £100 a week for a year, but £10 paid to GMB subs: 52 x £90 = £4680
plus
b) Six weeks on strike 6 x £0 = £0
plus
c) Six weeks on full pay + 30% overtime (accepting your assumption here as fact) 6 x £130 = £780
So: 1) taking no stance at all, and not bothering with union subs: £6400
2) going on strike for 6 weeks: £5460
So yes, maybe they're lazy, or maybe you're just talking out of your ignorant arse.
