They hope that if it gets bad enough the public will support another effort to privatise the company.
Many post workers have been in the job all their adult lives. We are committed to delivering a service based on need. The bosses and the government are in this for the short-term, and are only interested in profits.
But part-time work means part-time pay, part-time pensions, part-time sick pay – and part-time rights.
Post workers, on the other hand, are among the poorest in Britain. We earn around £100 less a week than the average skilled worker and many of us can only survive on overtime.
Now Royal Mail is telling us we have to accept a pay freeze – and that at least part of our overtime should be compulsory and free.
To get their way they are bullying and intimidating our members, and using managers and non-unionised casual staff in an effort to break our regional strikes.
Bosses everywhere are watching what happens in this dispute. If Royal Mail can drive the union out of the postal service, others will try to do the same.
The post workers’ strike is about drawing a line in the sand and telling any future government that we will not accept the smashing of our services.
If we are beaten, bosses everywhere will say: if we can take on the CWU and win, we can break you too. We must not allow them to do that.
