The Rail, Maritime and Transport union (RMT) members at 14 companies and Network Rail again walked out on Friday, crippling services across the country, a day after an unprecedented nursing strike.
However, some planned strikes have also been called off in recent days. Members of the Transport Salaried Staffs Association (TSSA) union at Network Rail have voted to accept the firm's pay offer, it was announced on Thursday.
And a planned 72-hour strike from Friday by ground handling staff at Heathrow Airport was suspended by Unite after private contractors Menzies made an improved pay offer. Planned strikes by security guards on Eurostar on Friday and Sunday have also been suspended after contractor Mitie made a fresh pay offer, the RMT has said.
