(Adds offer details, background)
Nov 23 (Reuters) - Royal Mail's parent firm,
International Distributions Services IDSI.L , on Wednesday
offered a pay increase of up to 9% over 18 months in its "best
and final" offer to its largest labour union, the Communication
Workers Union (CWU).
Royal Mail said it will make Sunday working optional and
offer "more generous" voluntary redundancy terms than originally
proposed, while also committing to no compulsory layoffs until
the end of March.
The revised offer comes after months of pay dispute between
Royal Mail and the CWU. The union has engaged in strike action
over multiple days in the past few months and recently announced
another 10 days of strikes between Nov. 24 and Dec. 24, a busy
period for the postal firm.
The CWU, which represents more than 115,000 postal workers
at Royal Mail, last month rejected a 7% salary increase over two
years.
The union did not immediately respond to a Reuters request
for comment.
