Were they really socialist policies? From what I know, which is hardly academic in nature, they were policies designed to stave off a potential revolution (or collapse). There was no real control on the part of the workers, just safeguards and promises of better treatment. Welfare is not necessarily socialist in nature, just something that occurs from socialist development because of workers looking out for each other. Having welfare given to you, without more direct involvement in how it’s dispensed, is less socialist than it is reactionary.
